The Bosch Rexroth COMPACT LIN. BUSH. KBC-40-NR (R065804030) is a high-quality compact linear bushing designed for general requirements with small outer dimensions and a highly compact construction. This model offers a high dynamic load rating and long service life, attributed to the hardened segmental load-bearing plates with ball conformity in the running track. The KBC-40-NR is characterized by its rust-resistant version, making it suitable for environments that demand higher resistance to corrosion, such as those found in the medical, chemistry, and food industries. With a standard radial clearance and non-greased setup, this linear bushing ensures low maintenance and is capable of high travel speeds of up to 5 meters per second. Its ease of mounting is one of its key features – it can be pressed on without the need for additional retention. The design includes many pockets that act as lubricant reservoirs which can extend lubrication intervals or potentially offer lubrication for life. These pockets also serve to collect any dirt ingress, thereby preventing jamming. The COMPACT LIN. BUSH. KBC-40-NR comes without seals and has an integrated metal retainer that is about 1 mm larger than the outer diameter of shaft diameters ranging from 3 to 50 mm to ensure a secure fit in the housing bore. It has a dynamic load capacity based on a total travel of 100 km; however, if based on 50 km, the capacity values should be multiplied by 1.26. This linear bushing's friction force starts at a minimum coefficient of 0.01 under heavy load conditions but may vary depending on load conditions. It operates within an ambient temperature range from -30°C up to +80°C and has an outer diameter D of 62 mm with a length of 80 mm. The product weighs approximately 0.4 kg and provides both minimum static and dynamic load capacities along with maximum capacities specified by Bosch Rexroth's standards for their Compact Series C products, ensuring reliability across various applications without compromising performance or durability.
